There is no record of a hummingbird attacking a human, but they will defend their territory fiercely from other birds and animals.
1. Introduction

In the United States, hummingbirds are generally seen as gentle and timid creatures. However, there have been reports of hummingbirds attacking humans. While the reasons for these attacks are not always clear, there are a few potential explanations.
One reason why hummingbirds may attack humans is if they feel threatened. Hummingbirds are very protective of their nests and territorial. If a person gets too close to a hummingbird’s nest, the bird may perceive them as a threat and attack.
Another potential reason for hummingbird attacks is if the bird is sick or injured. If a hummingbird is feeling ill or is injured, it may be more prone to attacking humans. Lastly, hummingbirds may simply be mistaken when they attack humans. It is not uncommon for hummingbirds to mistake a finger or other object for a flower or insect.
When this happens, the bird may try to grab the object with its beak, which can result in a sting. While hummingbird attacks on humans are not common, they can happen. If you are attacked by a hummingbird, it is important to remain calm and avoid making any sudden movements. If the bird does not seem to be backing down, you may need to seek medical attention as some hummingbird species can deliver a painful sting.
2. Defense mechanisms
There are a variety of reasons why hummingbirds might attack humans. One reason is that the hummingbird is defending its territory. Hummingbirds are very territorial creatures and will attack anything that they perceive as a threat to their territory, including humans. Another reason why hummingbirds might attack humans is that they are trying to protect their young. If a hummingbird perceives a human as a threat to its young, it will attack. Finally, hummingbirds might attack humans simply because they are afraid. If a hummingbird is afraid of a human, it might attack in order to defend itself.
3. Interactions with humans
Hummingbirds are the smallest birds in the world and are found in the Americas. Some species of hummingbird can be found as far north as Alaska and as far south as Chile. Hummingbirds are known for their ability to fly forwards and backwards, and their wings can flap up to 200 times per second. Hummingbirds are attracted to brightly coloured flowers and are important pollinators of many plants. They are also known for their aggressive behaviour when it comes to defending their feeding territories. Hummingbirds will chase away other birds, insects, and even mammals that come too close to their food source. Despite their small size, hummingbirds are not afraid to attack humans if they feel threatened. In one instance, a hummingbird repeatedly flew into a woman’s face, causing her to bleed from the nose and mouth. In another case, a hummingbird flew into a man’s eye, causing severe damage. While hummingbird attacks on humans are rare, they do happen. If you find yourself being attacked by a hummingbird, it is best to cover your face and head with your hands and walk away slowly. Do not try to swat at the bird or scare it away, as this will only make it more agitated.
4. Summary
No, hummingbirds do not attack humans. However, if a hummingbird feels threatened, it may swoop down and fly at a person’s face. This is usually done in defense of the bird’s territory.
Conclusion
They may if they feel threatened, but typically they are gentle creatures.
